Having described my invention what I claim as new and desire to secure by Letters Patent, is

1. A device of the character described comprising an interior cup; an exterior cup overlying and closing the interior cup, said cups adapted to be separated by their relative rotation in one direction, an independently rotatable member inside both cups, and a locking member comprising a spring pressed pawl carried by one cup, arranged to bite into the upper edge the other cup when said members are relatively rotated to separate them and thereby to prevent their separation thereafter.

2. A gear casing of the character described, comprising an upper and lower cup complementarily threaded, the upper cup enclosing the lower cup, and a spring pawl locking device secured at one of its ends in the top of the upper cup, the other end sharpened and bent down to bitingly engage the upper edge of the lower cup when screwed into position and .to prevent their separation thereafter.

In testimony whereof I hereunto subscribed my name.

SAMUEL L. TERRY.
